XIII. The Future of Man

If we occupy ourselves with the first problem it may seem to you audacious to try to speak about the future, or even that it is impossible to find out anything of the future of man. Nevertheless if you will consider the matter a little you will find that the view that one can know something about the future is not so unfounded after all. You have only to compare these things with what the ordinary researcher, the natural scientist, for example, can know with regard to future events. He can tell you definitely that if he mixes together oxygen, hydrogen and sulphur under certain conditions, sulphuric acid always results. One can say exactly what happens when one intercepts rays by a mirror. In fact, this goes even further in regard to things of external life; one can predict eclipses of the sun and moon for indefinitely long periods of time.
